To make both socks look the same wasn’t easy! I bought 2 balls of yarn in the same dye lot. Made my first sock without a cue that I’m going to suffer with the next one. The next sock was started with a new ball of yarn. Color transition was in the same order, but the length of each color was different. So, I had to cut the yarn when I notice that I have already enough of it in my sock, wind off some amount of yarn until necessary transition begins, start again. Luckily the yarn ball of my second sock had longer color transitions, not vs. And of coarse, keeping my first sock and comparing constantly was essential.
